Location: Rocky Run, a Brandywine River Tributary
Question: What is the relationship between steam velocity and changes in stream elevation/slope?
Hypothesis: As the elevation/slope of the stream increases the velocity of the stream increases.
Procedure: A member of the group used 5 meters of string and a fishing bobber to measure the amount of time it took the bobber to travel 5 meter in the center of the stream.
Graph the trial time data. Remember to label and title the graph. Include units. Use a different color for each trial.
Calculate the following:
Average Time for each location: Remember units.
Location 1:
Location 2:
Location 3:
Analyze the data.
Compare the slope/gradient to the average velocity. What observation can you make?
